News to me and I fished with all the Kinloss guys throughout all the 90's and early 2000's when I ran the Moray Fly Fishing League but might be true, however I do know they fished Morlich, Laggan, Insch and Garve for both species.
Local scientists suspect they've been in around ten years, introduced possibly from the Aviemore area. Whatever the case then it means the trout fishing will get really good before the biomass tips in favour of pike and trout fall into minority, exactly the same as the other waters where pike have been introduced (Skene, Morlich, Garve, Callatter, Alvie, Insh, Achnalalt etc) unless some form of management of the pike takes place. Sadly as the loch isn't run as a trout fishery anymore then it'll simply be left to fate and time to dictate now.
Pike are a magnificent fish there's no denying this, and a species I like to catch, however there's also no denying that selfishness, greed and ignorance are the actions of those who illegally introduce them to waters where they didn't exist before. After all do we not have enough easily accessible and well spread pike venues already without adding more?
Why don't we stick grayling in the Don, Deveron, Spey and Dee to see what the outcome would be? You'd be guaranteed world class grayling fishing that's for sure but I bet you would get a far bigger reaction to this than that of someone putting pike into a wild trout loch. Sadly the outcome is very different, grayling would co-exist to no real detrimental effect on both resident or migratory stocks, pike on the other hand...............
